call external, callable idl or linkimage ? [message #8184]

I am trying to figure out how to wirte a DLL (dynamically
linked library) for NT 4.0 containing a Fortran routine (built
using Fortran Powerstation) that can be called from IDL. The
problem is, is that I need this routine to call another
IDL routine and am confused about which style of linking with
IDL to use (i.e. call external, callable idl or linkimage)
I can't figure out any obvious way to combine call external
and callable idl to accomplish this and can't figure out how to
do this using linkimage (which I guess is the obvious choice
here) There dosen't seem to be any documentation or examples re.
how to do this.

If anybody has done anything remotely like this and could send
along some advice (or dare I hope, code fragments and compilation
flags...) I would be eternally in your debt. I'm not averse to
wrapping the Fortran routine in a Visual C++ wrapper if anyone
knows how to do it that way. (Rewriting either the IDL or Fortran
parts is not really an option as all the routines are rather
large and complex)

Thanks in advance for any tips or comments,

-- KY
